Action 2: Internal Repairs-- Fixing Solder Joints and Microswitches

If replacing the battery does not deal with the concern, the problem most likely lies within the internal electronics. Over years of day-to-day usage, the microswitches (the physical buttons soldered onto the circuit board) can break out from the board due to repetitive clicking pressure.

Tools Needed for Internal Repair:

• Precision soldering iron
• Solder wire and flux
• Magnifying glass or jewelry expert's loupe
• Replacement microswitches (if a switch is entirely broken)
• Isopropyl alcohol and cotton bud for cleaning

Step-by-Step Internal Inspection:

1. Open the Fob: Carefully take apart the outer plastic shell.
2. Check the Circuit Board: Examine the board under a magnifying glass. Look carefully at the metal legs of the buttons.
3. Recognize Cold Solder Joints: If a switch moves somewhat when nudged with a toothpick, the solder has broken.
4. Reflow the Solder: Using a heated soldering iron, touch a little dab of fresh solder to the connection points to re-establish electrical connection.
5. Clean the Contacts: Wipe down the rubber conductive pads and the circuit board contacts with isopropyl alcohol to get rid of grease and dirt buildup.
